What should be the first step in the procedure for parking a school bus?

The first step in the procedure for parking a school bus is to turn off all equipment switches. This is important to ensure that the bus does not inadvertently operate or drain battery power while parked. Turning off equipment such as lights, heating, or air conditioning helps prevent any electrical issues that could arise if they were left on. It also ensures that the bus is ready for the next time it is used, reducing unnecessary wear on the vehicle's systems.

After ensuring that all equipment is off, other safety protocols, such as checking for students, closing windows, and applying the parking brake, can be performed. However, prioritizing the shutdown of equipment is essential to maintain safety and proper function of the bus.
